EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 746,543, dated.December 03. Application filed June 23, 1903. Serial No. 162,725. (Nomodel.)

To-all whom it 77l/6ty concern:

Be it known that I, GABRIEL H. MAYER, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented new and useful Improvements in Eyeglasses, of which thefollowing is a specification.

My invention consists of an improvement in eyeglassesembodyinganose-piece or guard of substantially triangular form.

' It also consists in forming. the nose pieces or guards, the bow orspring, and the posts of eyeglasses of a continuous piece of wire, theoperation and advantages of said features being hereinafter described,and the novel features definitely set forth in the claims.

Figure 1 represents a perspective view of eyeglasses embodying myinvention. Fig. 2 represents a section thereof on line ac :c, Fig. 1.Fig. 3 represents an elevation of a portion of a modification.

Similar letters of reference indicatecorresponding parts in the figures.

Referring to the drawings, A designates the bow or spring; B B, thenose-pieces orguards; O O, the posts, and D D the straps, which aremembers of a pair of eyeglasses embodying my invention, said posts beingproperly se cured to said straps.

In carrying out my'invention I take a piece of suitable wire, preferablyround, the ends of which form the posts 0 O and bend portions of saidpieces at the inner terminals of said posts into triangular shapes,which constitute the nose-pieces or guards B B, the remaining portionbeing bent into the shape of the bow or spring A, the latter beingresilient and the several parts or members A B O composers of a singleor continuous piece of wire, which is properly soldered or otherwisesecured at the place of union of each post, nose-piece, or guard and anend of the bow or spring, thus firmly joining said parts and perservingthe shape of each, it being seen that the nose-pieces or guards are ofopen skeleton form. I

The straps are connected with the lenses E in any suitable'manner.

In Fig. 3 I show a nose-piece B of substantially triangular formprovided with an arm B composed of the ends of a piece of wire flattenedand united, said arm being adapted to be screwed or otherwise fastenedto a post D of usual style, but in either case only to the substantiallytriangular form of the nosepiece. The latter is easily adjusted, itconforms more closely to the anatomical contour of the nose,and holdsgently but firmly in position.

In the use of the word triangular as referring to the shape of thenose-pieces I inelude any shape substantially three-sided, the anglesbeing rounded off and the open or skeleton form of the pieces beingpreserved.

If desired, the inner sides of the nose-pieces may be faced with shell,cork, &c.

It will be noted that the skeleton nosepieces of triangular form are setat substantially a right angle with the plane of the lenses and spring,that one side of such triangle is preferably'in such vertical plane, andthat the other sides of the skeleton extend upwardly and inwardly. Thisform insures a consid erable contact with. the nose of the wearer.

sufficient to prevent slipping. -At the same time such contact is onlywith the upper or bony portion of the nose, thereby avoidinginterference with any of its other functions.

Various changes may be made in the de tails of construction shownwithout departing from the general spirit of my invention, and I do not,therefore, desire to be limited. in each case to the same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In an eyeglass, a skeleton nose-piece of the form of a triangle setat substantially a right angle with the plane of the lens, one side ofsuch triangle being substantially in such plane the other sidesextending inwardly and upwardly. I

2. In an eyeglass, a spring, skeleton nosepieces and posts made of acontinuous piece of wire, said nose-pieces being set at substantially aright angle with the plane of the other parts, each of said nose-pieceshaving its sides GABRIEL H. MAYER.
